We compare the derived photometric distances to the inverse of the Gaia parallax. For the comparison, we select \(\sim 355000\)  Gaia stars with small relative parallax uncertainties \(\sigma _\varpi /\varpi <0.1\)  since using \(1/\varpi \)  as the distance estimate only works for stars with high precision. The comparison is shown in Fig. 2, in which the zeropoint of the Gaia parallax, i.e., 0.017 mas [1]}, has been added to the parallaxes. There is close agreement between the two distance scales, with a ratio of approximately 0.842 of the photometric distances to the inverse of parallaxes. In this case, we calibrate the photometric distances to more proper ones by dividing them by 0.842.
